摘要

连续皮带机出渣系统具有输送能力强、运量大、安全、环保和自动化程度高等特点，已经广泛应用于TBM隧道施工，但在严寒地区存在冬季施工故障率高的问题。为了解决此难题，保障TBM正常施工，在辽西北供水工程中通过安装保温棚，对整条皮带机进行保温；在皮带机两端接渣、出渣特殊位置铺设保温被，加强其保温能力；在保温棚内部尤其是关键部位安装暖风机，进行加温供暖等方面的研究。解决了严寒地区冬季洞外皮带机防冻领域的技术难题，保证了TBM的顺利施工，取得了在严寒地区的皮带机冬季施工经验，以期为类似工程提供借鉴。

Abstract

The continuous belt conveyor system has many advantages, such as large transport capacity, safety, environmental protection and high automation. It has been applied to TBM tunnel construction widely. The fault rate of belt conveyor is high when it is used in cold areas in winter. As a result, a thermal insulation roof is adopted for belt conveyor used in Liaoxibei Waterdiversion Project. The thermal insulation problem of belt conveyor in cold areas in winter has been successfully solved and the safe and successful construction of TBM has been guaranteed. The results can provide reference for similar projects in the future.

Key words： TBM construction; cold areas; belt conveyor; thermal insulation
